Risperidone vs. Olanzapine as add-on Treatment in Treatment Resistant Depression
A Phase 1/2 study testing Risperidone and Olanzapine in people with Subjects Had Unipolar, Non-psychotic Major Depression, run by Sunnybrook Health Sciences Centre at 1 site in Canada.
Trial summary
Atypical neuroleptics may have antidepressant qualities in bipolar depression and in unipolar depression. Some data support the use of both Risperidone and Olanzapine, but there are no direct comparisons of their relative efficacy and tolerability in treatment resistant depression.

About this study
Official title: A Double Blind Pilot Trial to Evaluate Efficacy Trends and Safety of Risperidone and Olanzapine as add-on Therapy to Serotonin Type Antidepressants in Subjects With Treatment Resistant Depression (TRD)
Atypical neuroleptics may have antidepressant qualities in bipolar depression and in unipolar depression. Some data support the use of both Risperidone and Olanzapine, but there are no direct comparisons of their relative efficacy and tolerability in treatment resistant depression. The current study was designed as a pilot study to examine efficacy and tolerability of Olanzapine vs. Risperidone add on to a failed serotonin re-uptake inhibitor (SSRI) in depression.
Read the detailed description
Overview of Study Design
This is a Canadian, multicentre, double blind, comparator trial in 42 patients with TRD. TRD is defined as the failure to respond adequately to two successive courses of different antidepressants at an adequate dose (at least fluoxetine 20 mg, citalopram 20 mg, paroxetine 20 mg, sertraline 100 mg, fluvoxamine 150 mg, venlafaxine 225 mg)) for at least 4 weeks. All subjects, at entry to the study will be currently not responding to treatment of at least 4 weeks duration of a serotonin re-uptake inhibitor (SSRI) or a selective nor-epinephrine and serotonin re-uptake inhibitor (SNRI). Non-response is defined as a score of 3 ("minimal improvement") or worse on the Clinical global Impression of Improvement .
The objective is to assess the appropriateness of the trial design and to determine sample size requirements for future controlled trials. In addition the efficacy and safety of oral doses of risperidone (.5-3 mg/day) and olanzapine (2.5-15 mg.day) as add-on therapy to any SSRI or SNRI in treatment resistant depression will be evaluated. Subjects meeting the screening criteria will enter a 6-week trial with risperidone or olanzapine added on to the current SSRI or SNRI therapy.
A medical/ psychiatric history, HAM-D-29 (only the first 17 items will be used for outcome), MADRS and HAM-A will be obtained at screening. At subsequent visits HAM-D, HAM-A, and MADRS will be performed and adverse events (spontaneous and using the CASES checklist) and concomitant medications will be collected.
Recruitment:
Subjects will drawn from two sources:
- Outpatients currently attending the clinic at the sites. These subjects will already be in treatment or may have been referred from the local communities of the clinics involved in this study for consultation. Should these subjects drop out or once they have completed the study they will receive the treatment as usual at each site.
- Advertisements. Advertisements will be placed in local media (radio, television, newspaper) identifying the nature of the study and providing a contact number. These advertisements will be approved by the local IRB's prior to posting.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RisperidoneDrug
Risperidone will commence at 0.5 mg per day in a single daily dose given once in the evening. Clinicians will have the option, at each visit of increasing the risperidone dose to a maximum of 3 mg/day based on subject response and tolerability (please see Titration Recommendations below).
OlanzapineDrug
Olanzapine will commence at 2.5 mg per day in a single daily dose given once in the evening. Clinicians will have the option, at each visit, of increasing the olanzapine dose to a maximum of 15 mg/day based on subject response and tolerability.
| Study group | Role | What they receive |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Atypical neuroleptics may have antidepressant qualities in bipolar depression and in unipolar depression. Some data support the use of both Risperidone and Olanzapine, but there are no direct comparisons of their relative efficacy and tolerability in treatment resistant depression. The current study was designed as a pilot study to examine efficacy and tolerability of Olanzapine vs. Risperidone add on to a failed serotonin re-uptake inhibitor (SSRI) in depression.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Risperidone and Olanzapine in people with Subjects Had Unipolar, Non-psychotic Major Depression, run by Sunnybrook Health Sciences Centre at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from Baseline in Hamilton Depression Rating Scale at 1 week (time frame: day one). The study lists 18 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jan 2011.
